Separation of the infected person from the uninfected to prevent infection is?

Appeared in: IGIMS Staff Nurse - 2018

Explanation

Isolation is the correct term as it specifically refers to the separation of individuals who are confirmed to be sick or infected with a communicable disease.
The primary purpose of isolation is to contain the infectious agent at its source (the infected person) and prevent its transmission to susceptible individuals.
This is a fundamental public health measure for controlling the spread of many infectious diseases, as defined in epidemiology.

Option B: Disinfection is a process used to eliminate most harmful microorganisms from inanimate objects and surfaces. It does not apply to the separation of people.
Option C: Quarantine applies to the separation and restriction of movement of individuals who are not yet sick but have been exposed to a contagious disease. The question specifies an 'infected person,' not an exposed one.
Option D: Sterilization is a process that destroys all forms of microbial life, including highly resistant bacterial spores. It is used for surgical instruments and other critical medical supplies, not for separating people.

Clinical Relevance

Nursing practice connection: Knowing Infection Control and Prevention helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Nurses are on the front lines of infection control and are responsible for correctly implementing isolation precautions to protect other patients, healthcare staff, and visitors.
A clear understanding of the difference between isolation and quarantine is crucial for providing accurate patient education and for public health communication during community outbreaks.
What if? If the question had stated 'separation of a person who was exposed to an infected individual but is not yet showing symptoms,' the correct answer would be Quarantine.

How to Approach the Question

This is a definition-based recall question common in nursing exams.
Identify the most critical keyword in the question stem, which is 'infected person'.
Recall the precise public health definitions for the terms provided in the options.
Focus on the key differentiator: 'Isolation' is for the sick/infected, while 'Quarantine' is for the exposed but well.
Eliminate 'Disinfection' and 'Sterilization' immediately, as these terms relate to cleaning and decontaminating inanimate objects, not separating people.
